Product details
Overview
R7FA4T1B93CFL#AA0 from Renesas is a 32-bit Arm® Cortex®-M33 microcontroller operating at up to 100 MHz, featuring 128 KB code flash, 4 KB data flash, 40 KB SRAM, CAN FD, I3C, dual SPI, dual SCI, 12-bit ADC with PGA, dual 12-bit DAC, and TrustZone security - deployed in industrial motor control, smart sensors, and secure edge nodes.
For engineers reviewing the R7FA4T1B93CFL#AA0 datasheet, R7FA4T1B93CFL#AA0 pinout, R7FA4T1B93CFL#AA0 application, or R7FA4T1B93CFL#AA0 equivalent, this page delivers verified package mapping (48-pin LQFP), full pin function validation, real-world timing and analog performance values, and two confirmed alternative parts for design flexibility.
Technical Context
The R7FA4T1B93CFL#AA0 implements Armv8-M architecture with TrustZone, supporting secure/non-secure execution environments via dual MPU instances (8 regions each) and hardware-enforced memory isolation across flash, SRAM, and peripherals. Its clock system integrates PLL, HOCO/MOCO/LOCO oscillators, and CAC for accuracy monitoring.
It delivers deterministic real-time control via six GPT16E timers (including BLDC PWM outputs), two AGT timers for low-power event counting, and hardware-accelerated trigonometric functions (TFU) for motor and sensor algorithms - all coordinated by ELC and DTC to minimize CPU intervention.
